With this final subject, Primary Endpoint analysis is anticipated to begin in December 2026 and topline results are anticipated in Q1 2027. DURIPANC’s primary endpoint is Clinical Benefit Rate ("CBR"), defined as the proportion of patients achieving stable disease, partial response or complete response at 24 weeks following initiation of combination therapy.

Analysis of Secondary Endpoints is expected to begin in June 2027, or 49 weeks after this final subject received their first dose. DURIPANC’s Secondary Endpoints include Overall Survival ("OS") – the gold standard in oncology trials – as well as progression-free survival and immune profiling analysis that could potentially help identify subsets of future pancreatic cancer patients likely to experience the best survival results, which could be critical to the design of a pivotal Phase 3 clinical trial.

AIM Chief Executive Officer Thomas K. Equels stated: "AIM hopes to utilize the exploratory biomarker data generated through DURIPANC to design a Phase 3 study involving Ampligen in the treatment of pancreatic cancer. We are particularly interested in evaluating whether specific biomarkers may help to identify ‘super-responder’ patient subsets most likely to benefit from Ampligen-based therapy, thus supporting a more targeted and personalized treatment approach."

DURIPANC is a follow-up to the AIM/Erasmus Medical Center Named Patient Program utilizing Ampligen as a monotherapy in late-stage pancreatic cancer, where data suggested impressive improvements in survival, particularly when broken down by biomarker stratifications:

Based upon stratification for immune marker Neutrophil/Lymphocyte ratios less than 4.5, Progression-Free Survival ("PFS") of 17.7 months compared to 8.6 months for historical controls, for an improvement of 9.1 months in PFS
Based upon stratification for immune marker Neutrophil/Lymphocyte ratios less than 4.5, OS of 34.8 months compared to 12.5 months for historical controls, for an improvement of 22.3 months in OS
Based upon stratification for immune marker CA 19-9 less than 1000, PFS of 13.1 months compared to 8.6 months for historical controls, for an improvement of 4.5 months in PFS
Based upon stratification for immune marker CA 19-9 less than 1000, OS of 24.1 months compared to 12.5 months for historical controls, for an improvement of 11.6 months in OS
These results were accompanied by consistent reports of improved quality of life.

A multi-centre single-arm clinical trial involving all major paediatric oncology centres in Australia, with patients enrolled to determine the objective response rate to Deflexifol.
Recruitment of ten evaluable participants (aged 1-21 years) with refractory or recurrent paediatric ependymoma, including three participants currently evaluable from the phase I study.
Primary Objective: To evaluate the anti-tumour activity of Deflexifol as a single agent in patients with refractory or recurrent ependymoma.
Secondary Objectives: To assess overall survival and progression-free survival, and to further characterise the pharmacokinetics of Deflexifol monotherapy.
The phase II DART study is an Australian trial led by Principal Investigators Professor David Ziegler and Dr Marion Mateos and sponsored by the Australian and New Zealand Children’s Haematology / Oncology Group (ANZCHOG) in collaboration with FivepHusion. The phase II study follows the successful completion of the phase I DART study, the results of which were presented as a poster in November 2025 at the Society of Neuro-Oncology (SNO) Annual Meeting in Honolulu, Hawaii, USA. The phase II trial is designed to investigate Deflexifol monotherapy as a treatment for refractory or recurrent paediatric ependymoma. The trial is coordinated by the KOALA National Coordinating Centre at the Sydney Children’s Hospitals Network and all major Australian paediatric oncology centres are participating in the study. Significant trial funding has been provided by the Kids with Cancer Foundation and the Robert Connor Dawes Foundation.

Dr Christian Toouli, CEO and Managing Director of FivepHusion commented, "Paediatric ependymoma is the third most common brain cancer in children, and with no approved drugs to treat this condition, presents a significant unmet medical need for a safe and efficacious therapy. The ethics approval of the Phase II DART protocol is an exciting milestone towards our goal of evaluating Deflexifol as a promising therapy for these patients."

Deflexifol is an innovative next-generation novel co-formulation of 5-fluorouracil (5-FU) and leucovorin (LV), a drug that significantly enhances 5-FU anti-tumour activity. Deflexifol has previously been evaluated in the phase I DART study in paediatric brain cancer patients and two successfully completed clinical trials in adults with a variety of solid tumours. FivepHusion is harnessing the proven cytotoxic activity of 5-FU together with the unique, optimised attributes of the Deflexifol co-formulation to pursue Deflexifol development in a range of strategic solid tumour indications presenting with significant unmet medical needs, including paediatric ependymoma.

Ependymomas are rare central nervous system tumours (annual incidence of ~4 patients per million) that are more common in young children 0-4 years of age. The current standard treatment for ependymoma is surgery and radiotherapy, though relapse occurs in one third of all paediatric patients and is associated with a poor prognosis. Currently, there are no therapeutic drugs approved for the treatment of ependymoma, presenting a significant unmet medical need for the development of safe and efficacious new treatments for this disease.

Previously, 5-FU has been reported as a promising drug candidate for the treatment of paediatric ependymoma by independent research groups1,2, and in a clinical trial conducted at the St Jude Children’s Research Hospital (Memphis, Tennessee, USA)3. Recently, independent studies have gained further insights into understanding the susceptibility of paediatric ependymoma to 5-FU4. Research by FivepHusion collaborators indicates that Deflexifol, as a novel optimised co-formulation of 5-FU and LV, may be efficacious against paediatric ependymoma and other brain cancers. Due to its superior safety, tolerability and anti-tumour efficacy, Deflexifol offers the exciting opportunity to address the limitations of current 5-FU formulations to enable development as potentially the first approved drug for ependymoma and possibly other brain tumours.

While cryo-EM is now used routinely to determine structures of antibody complexes formed with compact and well-folded antigens, mapping antibody epitope footprints on small and flexible antigens remains highly challenging. In a new advance, Gandeeva scientists have determined the structure of a small and flexible antigen (< 20 kDa) bound to the Fab fragment of an antibody developed at Zymeworks. Of note, the team was able to visualize the nine amino acids that form the antibody-binding epitope at 2.6 Å resolution. The rest of the antigen is highly flexible and was not resolved in the reconstruction.

"Knowledge of the precise interactions at the binding interface of these types of challenging targets is incredibly useful for us in selecting antibody leads and provides us with crucial insights for the optimization of biologics", said Dr. Paul Moore, Chief Scientific Officer of Zymeworks.

"Our ability to obtain near-atomic resolution cryo-EM structures of the antibody binding epitope within flexible and structurally intractable proteins is a game-changer, especially in the context of accelerating design of AI-driven antibodies", said Dr. Sriram Subramaniam, Founder and CEO of Gandeeva Therapeutics. "Experimental validation by high-resolution and high-throughput cryo-EM using Gandeeva’s platform provides exactly the kind of rapid feedback that is essential for testing and validating antibodies derived by immunization and by computational design."

A total of 54 patients have now been enrolled in the study, representing half of the planned trial population. Recruitment momentum has accelerated significantly in 2026, with 11 patients enrolled in the first quarter and 17 patients recruited in the second quarter to date, marking the highest recruitment levels achieved in the study so far. Year-to-date recruitment of 28 patients has already surpassed total enrollment for 2025.

Four new sites have opened for recruitment in 2026 and in total ten hospitals across the United States, Spain, Norway, Belgium, the United Kingdom and Italy are currently active in the trial, and further site activations are ongoing to support continued recruitment.

"Reaching the halfway point for recruitment in our Phase 2 trial is an important milestone for Oncoinvent and reflects the strong commitment of investigators and study sites," said Oystein Soug, CEO of Oncoinvent. "We are pleased to see the steps taken to accelerate recruitment translating into the strong enrollment momentum seen in 2026. Building on the encouraging safety profile and preliminary efficacy signals observed in earlier studies, we look forward to further evaluating Radspherin’s potential to improve outcomes for patients with peritoneal metastases from ovarian cancer, who have limited treatment options following surgery."

The Phase 2 trial (ClinicalTrials.gov: NCT06504147) is a randomized controlled study evaluating the efficacy and safety of Radspherin in patients with peritoneal metastases from ovarian cancer. The primary objective is to compare progression-free survival between patients receiving Radspherin following complete surgical resection and pre-operative chemotherapy, and those receiving standard of care treatment consisting of chemotherapy and surgery alone.

Previous Phase 1 and Phase 1/2a data have demonstrated that Radspherin is well tolerated, with no dose-limiting toxicity observed at the recommended dose of 7MBq, and encouraging signals of efficacy. Results from the Phase 1 study in ovarian cancer have been published in the peer-reviewed journal Gynecologic Oncology, and results from the Phase 1/2a study in colorectal cancer have been published in the peer-reviewed journals Journal of Surgical Oncology and Frontiers in Medicine.
